Krohn Conservatory is located in Cincinnati, Ohio. It houses over 3,500 plant species from all over the world. Inside, you can find a replica of a rainforest, a desert, and a conservatory with a beautiful collection of orchids. One of my kids' favorite seasonal displays, is the Butterfly Show held from mid-April to June. Pictured below is the gingerbread house Christmas display. Hours are from 10-5 PM.
